Answer:
The linear velocity is 
Explanation:
According to the law of conservation of energy
The potential energy possessed by the hoop at the top of the inclined plane is converted to the kinetic energy at the foot of the inclined plane
The kinetic energy can be mathematically represented as
Where 
is the moment of inertia possessed by the hoop which is mathematically represented as
Here R is the radius of the hoop
is the angular velocity which the hoop has at the bottom of the lower part of the inclined plane which is mathematically represented as
Where v linear speed of the hoop's center of mass just as the hoop leaves the incline and rolls onto a horizontal surface
Now expressing the above statement mathematically
=> 
=> 
=> 
=> 
Substituting values
The observed differences in amplitudes are due to interference between the sound waves. The decrease in amplitude is due to destructive interference of the waves and the increase in amplitude is due to constructive interference.
Corrosive substances are rarely harmful to human skin. This statement is <em>False.</em> Corrosive substances are ALMOST ALWAYS harmful to the skin.
Most problems addressed by the technological design process have only one solution. This statement is also <em>False.</em> There is more than one way to skin a cat.
Magnetic force = charge × speed × magnetic field
Fm = (1.6x10^-19)(3x10^6)(0.02)
Fm = 9.60x10^-15 N
^That is the magnitude of the magnetic force. If you want the direction, you will need to know what direction the speed and magnetic field are. Then you can use the left hand straight fingered rule to determine the direction of the force.
